TIME-STRIKING WATCH.

SPECIFICATION forming part of Letters Patent No. 425,582, dated April 15, 1890.

Application filed February 10, I887. Renewed September 16, 1889- Serial No. 323,996. (No model.) Patented in England October 18, 1886,1I0. 13,267, and in Canada May 1,1887,No.26,436.

To all whom it may concern:

Be it known that I, J osnrn ROBINSON, a subject of the Queen of Great Britain, residing at Maryport, in the county of Cumberland, England, have invented certain new and useful Improvements in the Construction of Keyless \Vatches, (for which I have previously obtained Letters Patent in Great Britain, dated October 18, 1886, No. 13,267, and in Canada, dated May 1, 1887, No. 26,436,) of which the following is a full, clear, and exact description.

This invention has relation to watches of that class usually known as stem-winders, and has for its object to provide a stem-winding watch by which the time will be indicated by means of a sounder or bell operated by means of the stem or winding apparatus of the watch.

This invention therefore consists in the construction, combination, and arrangement of parts, more fully described hereinafter, and specifically pointed out in the claims.

In the accompanying drawings, which illustrat-e my improvements as applied to that type of watches usually known as the VVaterbury watch, Figure 1 is a plan View of a watch case and shank with striking-hammer attached in position to be operated directly from the winder. Fig. 2 is a side view of the same with a portion of the case broken away; Fig. 3, a View of the stem and attached pinion; Fig. t, a view of the gong or hell. Fig. 5 is a view of a modification, in which the striker is operated by means of a pin or pins inserted in the face of the rear plate of the watch-movement; and Figs. 6, 7, 8, 9, and 10 are detail views.

In the class of watches herein described and illustrated the winding apparatus consists of a button H, attached to a shaft E, which carries a pinion O, which gears with teeth upon the periphery of the back winding-wheel A of the watch-movement, and, as will be seen, when the button H is rotated it will wind up the spring which is attached to the winding-wheel A.

In my proposed form of movement I construct the winding-wheel A with sixty teeth upon its periphery and the gear O with twelve teeth, so that five full turns of the button II will cause the winding-wheel A to revolve once; but I do not wish to confine myself to this exact construction, as I may vary the number of teeth upon the pinion O without departing from my invention.

As will be understood by those who are familiar with the construction of this type of watches, the winding-wheel A makes a complete revolution each hour, and accordingly in order to determine what length of time has elapsed since the watch has been wound up it is only necessary to ascertain how many full revolutions have been made by the winding-wheel A, and this I accomplish by the following means: A pin B is attached to the face of the pinion O, and a hammer or striker D is pivoted within the case of the watch, its upper end 6 being in the line of the pin B and its lower end or head in position to strike again st the inner side of the case or on the bell J. At each complete revolution of the pinion O the hammer or striker will be raised by means of the pin B and caused to strike the case or bell J. As before described, if the pinion O has twelve teeth and the winding-wheel A has sixty teeth, five strokes of the hammer will indicate a complete revolution of the winding-wheel A, and by counting the number of strokes of the hammer or striker one can correctly determine the number of revolutions made by the winding-wheel A, and thus determine the length of time that has elapsed since the spring was wound up.

In the modifications illustrated in Figs. 5

- to 10 of the drawings the pin by which the In addition to the pins in the face of the winding-wheel A, I also provide a spring-dog F, working in the teeth of the winding-wheel A, which will indicate each separate tooth wound up or each minute that has elapsed.

The operation is' as follows: If it is desired to know the time without looking at the hands or dial, remember the time at which the watch was last wound. The stem is then turned, and at each complete revolution of the winding-wheel A one hour is indicated as having elapsed, and as the wheel A has sixty teeth the number of clicks made by the springpawl F will indicate the number of minutes in addition to the hour or hours as indicated by the strokes of the bell or gong, and by a simple mental calculation the correct time can be determined. Suppose, for instance, that the watch has been wound completely up at ten p. m., and during the night it is desired to know the time. The watch is wound up, and at each complete revolution of the wheel A the bell or gong is sounded. In this case the gong strikes four times, indicating thereby four revolutions of the wheel A, or four hours, as having elapsed. Then the click of the pawl F is counted to determine the minutes, and it sounds twenty times, thus indieating that four hours and twenty minutes have passed since the Watch was previously wound. By adding the four hours and twenty minutes to ten p. m., the correct-time, 2.20 a. m., is indicated.

Different intervals of time can be indicated by the different arrangements of the pins in the wheel, as before described.

WVhat I claim is 1. The combinatiomwith the winding mechanism of a timepiece, of a sounder operated through the medium of said winding mechanism, and thereby indicating the revolutions of the winder, substantially as shown and described.

2. The combination, with the Winding mechanism of a time-piece, of a sounder and a pivoted striker and intermediate mechanism, substantially as shown and described,whercby each revolution of the winding mechanism will operate said striker one or more times,

as set forth.

3. The combination, with winding-Wheel A and its operating mechanism, of a pin or pins pins, whereby the revolutions of the plate will operate the striker, substantially as shown and described.
